FARENHYT IDP-FIRE-CO-W Smoke, Heat and CO DetectorThe IDP FIRE CO W is a plug in, addressable device that provides both fire and carbon monoxide (CO) detection. For fire, the detector combines four separate sensing elements in one unit (smoke, CO, light flame, and heat) to sense multiple components of a fire. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulate. For CO, the detectors electrochemical sensing cell creates a separate signal for life
